We all were taught early in school that the Earth orbits the Sun…that its path is elliptical…that because of the tilt in Earth’s axis of rotation, we have seasons as the Earth orbits our star annually. Because of the elliptical orbit, and because the ratios of land to ocean are different between the Northern and Southern Hemispheres, we might expect that global average surface temperatures would vary over the course of a year.

Later in life we’ve been brow beaten with alarmism about human-induced global warming and climate change…that the Earth will become a literal—not figurative—hell if global surface temperatures rise—formerly 2-deg C—now 1.5 deg C above pre-industrial levels. But does the average person know much global surface temperatures vary annually as it orbits the Sun? It’s unlikely, because I’ve never before seen graphs that are similar to what’s presented in this post or seen it discussed in any of the global warming literature. Am I expecting most persons to find this information to be of any interest? Nope. I simply find it noteworthy that, as I mentioned before, I’ve never seen it presented anywhere. In fact, I just Googled, in quotes, “How Much Do Global Surface Temperatures Cycle Annually?” and Google replied (their boldface), “No results found for “How Much Do Global Surface Temperatures Cycle Annually?”.
